"The track of the storm will be key, but as of Wednesday morning, it looks like the state will be split, with snow to the north, a mix of sleet and freezing rain across the middle of the state and then rain to the south," said StormTeam 6 meteorologist Todd Klaassen.

Several weather models are calling for a substantial amount of precipitation, though there are variances in both amount and whether it falls as snow, sleet, freezing rain or rain.

Where the storm system develops and tracks will determine what type of precipitation will fall where you live, and the amount of moisture that gets drawn into the system will determine how much falls.

"This storm will likely cause significant travel issues throughout the day Sunday and into Monday morning, when all precipitation changes back over to all snow," Klaassen said.

The Sunday-Monday storm will be preceded by some light snow from a weaker system Friday.

Behind the weekend storm system, another blast of cold air will move into the region from the north, with highs on Tuesday expected to stay below 20.
